The eks snap packages all the Kubernetes binaries of Amazon EKS Distro (EKS-D) and combines them with a MicroK8s like experience, for an opinionated, self-healing, highly available EKS-compatible Kubernetes anywhere.
To form a multi-node cluster call eks add-node on any existing cluster member to get a token, followed by eks join <token> on the new machine.
For optimal compatibility with EKS, this Kubernetes distro will launch a very specific set of component services automatically. These provide a standardised K8s environment that simplifies workload compatibility with EKS on AWS itself.
When you initialize the cluster, it will also fetch and enable:
coredns - DNS services for services on this EKS cluster
metrics-server - K8s Metrics Server for API access
storage - Storage class; allocates storage from host directory
The EKS snap will automatically detect if it is on AWS, and if so it will also enable:
aws-iam-authenticator - login to your cluster with AWS IAM credentials
Stripped down MicroK8s with EKS components
This EKS Distro is based on MicroK8s. It has a stripped down set of addons and is designed to feel great for AWS users only. It assumes you have AWS IAM credentials for identity and provides default services that are compatible with EKS on EC2. See eks status for component information.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
